  • the present invention relates to a mobile communication system, a base station, a mobile terminal, a notifying method, a program and a recording medium, and more particularly relates to a method of notifying that an HSDPA (High Speed Downlink Packet Access) communication is possible, to the mobile terminal.
  • HSDPA High Speed Downlink Packet Access
  • a DPCH Dedicated Physical Channel
  • a base station control apparatus such as an RNC (Radio Network Controller) is connected to the base station.
  • the mobile terminal always receives HS-SCCH (High Speed Shared Control Channel) data of 4 channels specified by the base station, and detects a mobile terminal ID (Identifier) included in the data transmitted on HS-SCCH and determines whether or not the detected mobile terminal ID is coincident with a mobile terminal ID of the self-station.
  • HS-SCCH High Speed Shared Control Channel
  • the mobile terminal uses a control data transmitted through the HS-SCCH and receives a signal transmitted on HS-PDSCH (High Speed Physical Downlink Shard Channel) in a delay of a predetermined time from the reception of a signal on the HS-SCCH.
  • HS-PDSCH High Speed Physical Downlink Shard Channel
  • the mobile terminal and the base station immediately transmit it by using DPCH (UL/DL) (for example, this is noted in “3GPP TR (Technical Report) 25.858, V5.0.0, March 2002”).
  • a network determines a maximum communication capacity (bit rate) at the time of the transmission by the mobile terminal and communication resources and instructs an HSDPA communication start to the mobile terminal, if the HSDPA communication is possible.

Thus, until a throughput after the packet communication connection is confirmed, it is impossible to determine whether or not the HSDPA communication is possible. In particular, in a waiting state or in a low rate communication state, whether or not the HSDPA communication is possible cannot be determined.
